y=x-2 y=-2x+7
substituting for y in the second, we have
x - 2 = -2x + 7 add 2x to both sides and add 2 to both sides
3x = 9 divide by 3 on both sides
x = 3
So....y = 3 - 2 = 1
So the answer is (3, 1)
Y can't be two things
Indeed. What you are saying is
$$x-2=2x+7$$
Awkward Moment, when you didn't see it.
Ugh tired.
Don't worry, TM.....I made a silly error myself this morning on a problem....it happens to everyone.......
